Abstract

This demonstration presents an adaptive visual marker optimised to improve tracking performance in Spatial Augmented Reality environments. The adaptive marker uses a color light sensor to capture the projected light color from a SAR system. The color information is used to select the optimal tracking color that is displayed on a diffused Red, Green, Blue Light Emitting Diode marker attached to a user´s finger. We have selected to use the visible light spectrum for the marker since it can be leveraged to present visual feedback to support user interface interactions in addition to the tracking system operation. Our initial results have shown a performance improvement compared to a fixed color passive marker.
